Summary of the invention
The present invention provides a kind of cold wind access device, which can effectively adjust the inlet air temperature of ventilation blower, improve
The cooling effect of ventilation blower.
The present invention is implemented as follows:
A kind of cold wind access device, to be mounted on the air inlet of ventilation blower, wherein it include: installation pedestal, the installation
Pedestal is set on the air inlet of ventilation blower;Connecting rod, the connecting rod include first end and the second end, the connecting rod
First end connect with the installation pedestal, the second end of the connecting rod is connect with cold air duct interface;Cold air duct
Interface, to access cold wind and cold wind is supplied to the air inlet of ventilation blower.
The beneficial effects of the present invention are: the entrance by setting cold air duct interface as cold wind, so as to reduce air inlet
Machine inlet air temperature;By the way that connecting rod is arranged between cold air duct interface and ventilation blower air inlet, which can surround rectangle
Opening, to be used to supplement air quantity for ventilation blower as room temperature wind entrance;The hollowed out area of connecting plate also can be used as room temperature wind entrance;
By being passed through for comprehensively control room temperature wind and cold wind, thus the purpose of adjustable intake and inlet air temperature.

Specific embodiment
To keep the purposes, technical schemes and advantages of embodiment of the present invention clearer, implement below in conjunction with the present invention
The technical solution in embodiment of the present invention is clearly and completely described in attached drawing in mode, it is clear that described reality
The mode of applying is some embodiments of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ability
Domain those of ordinary skill every other embodiment obtained without creative efforts, belongs to the present invention
The range of protection.Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit below and is wanted
The scope of the present invention of protection is sought, but is merely representative of selected embodiment of the invention.Based on the embodiment in the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts belongs to this
Invent the range of protection.
In the description of the present invention, term " first ", " second " are used for description purposes only, and should not be understood as instruction or dark
Show relative importance or implicitly indicates the quantity of indicated technical characteristic.The feature of " first ", " second " is defined as a result,
It can explicitly or implicitly include one or more of the features.In the description of the present invention, the meaning of " plurality " is two
It is a or more than two, unless otherwise specifically defined.
Referring to Fig.1 shown in -3, the embodiment of the present invention provides a kind of cold wind access device, comprising: installation pedestal 100, connection
Bar 200, and cold air duct interface 300.One end of the connecting rod 200 is connect with the installation pedestal 100, the connecting rod
200 other end is connect with the cold air duct interface 300.
The installation pedestal 100 plays the role of being fixedly connected.The installation pedestal 100 and ventilation blower (not shown)
Air inlet is held out against by bolt and is fixedly connected.Cold wind access device is fixed on the air inlet of ventilation blower by installation pedestal 100.
Specifically, it is provided with card slot in the installation pedestal 100, the edge of the air inlet of ventilation blower can be mounted on.
The connecting rod 200 connect with the installation pedestal 100 and is fixed in the installation pedestal 100.The connecting rod
200 are connected through a screw thread with the installation pedestal 100.Specifically, the connecting rod 200 include four connection single poles, this four
It connects single pole in parallel and interval is arranged, and every connection single pole is individually connect with the installation pedestal 100.Further, the company
Extension bar 200 is perpendicular to the plane where the installation pedestal 100, and four connection single poles are where the installation pedestal 100
Subpoint in plane can connect into a rectangle.
The cold air duct interface 300 pays connection by nut lock with connecting rod 200.The cold air duct interface 300 wraps
Include first port and second port.It is provided with connecting plate in the first port, to be connected and fixed connecting rod 200.The connection
Plate includes hollowed out area and non-hollowed out area.The connecting rod 200 is fixed on non-hollowed out area.The second port is set with refrigeration
Standby connection, the second port are used as cold air inlet.
When work, cold wind enters from the second port of the cold air duct interface 300, by cold air duct interface 300, even
Extension bar 200, installation pedestal 100 enter to the air inlet of ventilation blower, and then achieve the purpose that reduce ventilation blower inlet air temperature.Together
When, in the space between the cold air duct interface 300 and installation pedestal 100, every two adjacent connection single poles can be formed
One rectangular aperture, and multiple rectangular apertures that the connecting rod 200 is formed can be used as room temperature wind entrance 2, and cold air duct interface
Hollowed out area on 300 connecting plate can be used as room temperature wind entrance 1.Therefore, when the air quantity of ventilation blower is not achieved in cold wind air quantity,
Insufficient air quantity can be supplemented by room temperature wind entrance 1 and room temperature wind entrance 2, avoid the air quantity for influencing ventilation blower.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
